Dell and Overstock lead consistency ratings for February

Dell.com had the best consistency score for Internet Explorer testing among large retailers tested in February, says Compuware Gomez. Last month, the retailer had the most consistent Internet Explorer site loading time with a variation of 0.72 seconds. Overstock.com had the best Firefox consistency score at 0.75 seconds.

In Firefox testing, LLBean.com came in second place behind Overstock.com with a deviation of 0.84 seconds. Apple.com trailed in third place (0.91) and was followed by QVC.com (0.99) and OfficeMax.com (1.07).

The average Internet Explorer consistency score among the 22 retailers measured in August was 1.69 seconds. The same group of retailers produced an average Firefox score of 1.60 seconds.

The consistency ratings take into account differences in the speed of web page delivery across multiple visits.
